I'm not a big fan of USSR electronics, I had several things like a reel-to-reel tape deck, a small TV and a
bench power supply. The stuff worked, but some of the technical details were just...well, weird.
The tape deck used the kind of brown string that was used to sling arround parcels as brakes for the reels,
the plastic was spongy and wobbly, the TV turned into a radio after it got hit by a falling plug of a extension
cord and the psu used fuses made from paper. They cought fire when burning out, taking the whole fuse
holder with them. I replaced them with standard parts, then one of the power transistors died. It had the
weirdest of cases I have ever seen, like a small tin with leads hanging from the bottom. After that I chucked
the thing out.
All old soviet electronics I have yet seen sported rather dubious build quality.
